The interesting thing is why Kindle is selling so well, and why exposure to an actual unit seems to convert people far more quickly than one would expect from similar units (the sony version though slicker looking is not doing nearly as well). My take is that, as with the iPod it's the service element that makes the device (any book you want, any time you want, any where you want) so compelling. And I've seen a fair amount of anecdotal evidence of non-geeks confiscating Kindle's from early adopters; which coupled with the Kindles decidedly unsexy design suggests that there is a much deeper pent up demand for what the kindle has to offer than there was for the ipod. It's a big wave forming up and it's ripe for riding; what could be built to supply the Kindle Ecosystem?
